T 0 all whom t may concern Be it knownthat I, JAMES `A. Conax, a Subject of the King of Great Britain, and resident of the city of Ottawa, in the )Prov-` ince of Ontario and Dominion of Canada, have invented certain new and useful 1mprovements in Railway Water-Closets, of which the following is a full, clear, and yex'- actdescription. l

This invention relates to improvements in railway closets, and the object of the invention is to provide a reservoir and controlling means therefor of vsimple and durable construction which will bev readily accessible, from the exterior ofthe car, for repairs.

A further object is to provide a device of this class which will be absolutely proof against freezing. i

The device consists briefly of a reservoir having a double bottom forming a heating jacket. The reservoir is provided with a closure plate, the, upper surface of which is at ioor level and which is adapted to support the usual hopper. kA valve casing is secured to the lower part of the reservoir and forms a closure and outlet for the heating jacket. A valve is located in the casing to control discharge from ythe reservoir.

In the drawings which illustrate thel inventionz Fig. 1 is a plan view of the device.

Fig. 2 is a section on the line 2A-2,I Figl ure 1.

Fig. 3 is a fragmentary section on the line 3 3, Figure 2.

Referring more particularly to the drawings, 11 designates the ioor of a car and 12 a reservoir supported by an outwardly projecting flange 13 which rests in a rabbet 14 in the floor. The walls of this reservoir are substantially vertical in their upper portion 15 and converge towards the centre in their lower portion 16 leaving a comparatively large outlet aperture 17 at the bottom of the reservoir. Outside the converging reservoir walls 16 are surrounding walls 18 enclosing a jacket space 19 which is open at the bottom of the reservoir. A valve seat 20 is secured to the lower edges of the walls 16 and 18 and closes the jacket space. This seat includes a hollow casing portion 21 adapted to receive the valve gate 22 during open valve position. A passage 23 establishes communication between the jacket and the interior of the casing portion 21 and.

a' suitable number of drainage'holes 24 are provided in the said Acasingportion for the emission of spent heating agent. f

The valve gateslides on 4guides 25 `formed in the seat'20, which guides are providedat y suitable intervals with cam portions' 26 adapted to press the valve gate tightly against a gaskety 27v mounted, in the casing 20. The leading end of thevalve'is provided with a down-turned, inclined flange 28 which serves' to stiften the leading end of the gatejwhere it is unsupported by'therguides and where it obviously cannot be supported.v The inclined flange also will not provide lodgement for matter escaping from the reservoir. The gate is operated by a spindle 29 passing out of the casing portion 21 through a stufling box 30 and connected` to any suitable operating mechanism 31rwhich ymaybe* in part supported by a plate 32 connected to the casing 20. l

The reservoir is provided at the to with a cover plate 33 havinga suitable anged aperture 34 above which an ordinary hopper is mounted. Attached to the lower side of the cover is a fiushingpipe 35 having outlet apertures'36 directed `against the vertical sides of the reservoir. This ipe is connected with a water supply pipe 3 At any suit. ablepoint an laperture 38 `is provided for the reception of a vent pipe. At the upper part of the reservoir an aperture 39 is provided communicating with. a 4downwardly extending passage 40 open at its lower end.T

An opening 41 is provided below the con verging walls 16 for the connection of a pipe to supply steam or any heating agentto the jacket 19.

The operation of the device is extremely simpie. The reservoir and cover plate are secured to a car floor and will never require to be moved unless broken. The reservoir occupies the depth of the car underframe and is substantially protected thereby. The only point at which freezing is liable to kprove troublesome is at the discharge where the contents are consolidated by the oonverging Walls and are exposed to the outer air. This is overcome by the provision of an ample heating jacket which warms the reservoir, over-flow and valve. Tf it becomes necessary to clean or repair the device this may easily be accomplished from the outside of the car and the entire valve structure may be removed if desired, thus sci ' voir.

exposing the interior of the steam jacket. The connection betvveen the over-flow and reservoir may, ifi'plugged, be cleared from the outside by inserting a suitablein's'trument "through" theV straight over-flow pipe. When the valve is open it runs easily and freely on the guides and Without any friction on the gasket. In the inalstages of the closing movement the valve rides up on the cams 26 and is thus pressed against the gasket making an absolutely tigllit oint. It ,will be noticed from Figure l'that tlm link connection betvveen the'valve 1and p-y e-rating Agear vwill permit the gear to be placed in V'any position relative to the reser y If the reservoir is made square or circular the cover carrying the .Hush pipe arid'veut may be "Placed 'iu uuy VP,0.Slt0n `rela tiret@ t-hezbQdY-Of the, ruser'iui'rf "Having thus deSC-.ribed'my u'VeutiQ-u, what Iclamis v Y 1`.-`In fa device of the class described, a reservoir, a heating jacket surrounding .the reservoir,'thereservoir and jacket being open at the lovver end, andra valve Seatv secured lto the bottom of the reservoir and fuuu'g e Closure for the heatiue jauktf 2.A In a'device of the class described7 a reservoir, a' heating jacket surrounding' the reservoir, a valve'seat' and'casing secured tothe bottom of the'reservoir and forming a closure for the heating jacket and a'drainf age outletfor the'jacket establilshedthi'ough upper part of said reservoir, the lower part of said pipe being vdisp'osedto be heated from the reservoir heating jacket.'
